This should describe also what a "filtered entry" exactly is. It's not clear

Commit 3e6c6f630a5282df8f3393a59f10eb9c56536d23 ("Delay creation of
khcvd thread") moved the call of hvc_init from being a device_initcall
into hvc_alloc, and used a non-null hvc_driver as indication of whether
hvc_init had already been called.
The problem with this is that hvc_driver is only

The use of __initcall is to be eventually replaced by choosing
one from the prioritized groupings laid out in init.h header:
pure_initcall 0
core_initcall 1
postcore_initcall 2
arch_initcall 3
This series had an interesting genesis in chain on effects, typical
of how things can creep and spill over.
I wanted to clobber pointless instances of #include

fully complete that, I had to plan to move module_init into module.h;

This patch contains the new definitions necessary for grant mapping.
v2:
- move unmapping to separate thread. The NAPI instance has to be scheduled
even from thread context, which can cause huge delays
- that causes unfortunately bigger struct xenvif
- store grant handle after checking validity
These counters help determine how often the buffers had to be copied. Also
they help find out if packets are leaked, as if "sent != success + fail",
there are probably packets never freed up properly.

This patch changes the grant copy on the TX patch to grant mapping
v2:
- delete branch for handling fragmented packets fit PKT_PROT_LEN sized first
request
- mark the effect of using ballooned pages in a comment
- place setting of skb_shinfo(skb)->tx_flags |= SKBTX_DEV_ZEROCOPY right
before
These became obsolate with grant mapping. I've left intentionally the
indentations in this way, to improve readability of previous patches.
v2:
- move the indentation fixup patch here
v4:
- indentation fixes

These counters help determine how often the guest sends a packet with more
than MAX_SKB_FRAGS frags.

Xen network protocol had implicit dependency on MAX_SKB_FRAGS. Netback has to
handle guests sending up to XEN_NETBK_LEGACY_SLOTS_MAX slots. To achieve that:
- create a new skb
- map the leftover slots to its frags (no linear buffer here!)
- chain it to the previous through
A long known problem of the upstream netback implementation that on the TX
path (from guest to Dom0) it copies the whole packet from guest memory into
Dom0. That simply became a bottleneck with 10Gb NICs, and generally it's a
huge perfomance penalty. The classic kernel version of netback used
Unmapping causes TLB flushing, therefore we should make it in the largest
possible batches. However we shouldn't starve the guest for too long. So if
the guest has space for at least two big packets and we don't have at least a
quarter ring to unmap, delay it for at most 1 milisec.
v4:
- use bool
A malicious or buggy guest can leave its queue filled indefinitely, in which
case qdisc start to queue packets for that VIF. If those packets came from an
another guest, it can block its slots and prevent shutdown. To avoid that, we
make sure the queue is drained in every 10 seconds.
The QDisc
RX path need to know if the SKB fragments are stored on pages from another
domain.
v4:
- indentation fixes
